Today the red band trailer for the Will Ferrell and Adam McKay produced comedy Bachelorette hit the web and it's a doozy!

The upcoming film, debuting in limited release on September 7, follows three female friends as they prepare for a wedding.

I know what you're thinking: This looks like Bridesmaids. While admittedly very similar (even the title is pretty much a synonym), I'm going to tell you the difference:

1.) Bachelorette mostly focuses on one night, featuring one heck of a bachelorette party.

2.) In this movie, the bridesmaids are three women who used to bully the bride (played by Bridesmaids actress Rebel Wilson) in high school.

Judging by the trailer, it's probably a tad more Hangover-ish than Kristen Wiig's highly acclaimed summer blockbuster.

The movie stars Rebel, Kirsten Dunst, Lizzy Caplan, Isla Fisher, and Adam Scott.
